UNITED STATES PATENT OFFICE ANTONIO FAZIO, OF PORTLAND, OREGON SEEDINGATTACHMENT FOR TRACTORS Application led October 26, 1927. Serial No.228,773.

This invention relates generally to agriculture, and particularly to anattachment for tractors adapted to facilitate seeding, fertilizing andcultivating all crops planted in rows.

The main object of this invention is the saving of time for the farmer.

The second object is to make it possible to plant the seed at any depthdesired with extreme uniformity of planting.

The third object is to permit the planting of the seed at the correcttimethat is, when the ground is in the right condition, owing to thefact that less time is required than under existing conditions.

The fourth object is to make it possible' to have all of the rowsplanted exactly parallel with each other, or at least sufficiently sofor all practical purposes.

rlhe fifth object is to eliminate the usual loss of land at the ends ofthe rows by permitting planting to the extreme end of each row.

The sixth object is to facilitate cultivation by making the rowsparallel for use with either power or hand cultivators.

rlhe seventh object is to improve the condition of the ground whileplanting owing to the fact that the machine itself acts as a clod masherif passed over the soil at the right time, which is the ideal conditionfor seeding; whereas undesirable results would follow if a heavy tractorwere passed over the ground before or after such condition was reached.

The eighth object is to secure a great economy in labor, since one manwith a tractor can do as much work as thirty-five can do by hand withless fatigue and with a greater degree of accuracy than it would bepossible bv the most expert hand seeder.

The ninth object is to: so construct the device that it can be readilyattached toV or removed from the tractor by any unskilled person withoutthe use of any tools other than an ordinary wrench.

These, and other objects, will become more apparent from thespecification following as illustrated in the accompanying drawings,

in which:

Fig. 1 is a side elevation of one form of the device in which power is"supplied from the tractor wheels, in which form the seeder is hinged onthe shaft wlhich drives the seeder mechanism. Fig. 2 is a plan of thedevice showing the clutch throw-out from which the lifting bars areomitted. Fig. 3 is a section taken along the line 3--3 in Fig. l. Fig. 4shows a modification which is similar to that shown in Fig. 1 exceptthat the seeders are driven by sprockets on one shaft and hinged on aseparate bar. Fig. 5 illustrates a hoe attachment and its, connection tothe device. Fig. 6 is a perspective view of a portion of the operatingchain showing the removable connection.

Similar numbers of reference refer to similar parts throughout theseveral views.

Referring in detail to the drawings,it will be observed that themechanism is driven from therwheels 13 of the the tractor itself. Inorder to make this possible there is pro-` vided a bracket 50 whichcarries the angle bar 51, over which is mounted a square shaft 52 and around tubular shaft 53. The square shaft 52 and the round tubular shaft53 journal in the bearings 53-A which are mounted on the bracket 50. Onthe shaft 52 is placed a slidable sleeve 54 on which is rotatablymounted the arm 55, which carries the forked beam 56 on which is mountedthe seed hopper 57. The operating chain 58, which passes aroundthesprocket wheel 59 of the seeder, is driven from the sprocket wheel 60on the shaft 52. Rotary motion is supplied to the shaft 52 by thesprocket wheel 61 through the chain 62 which passes around the sprocketwheel 63 which is attached to the drivel wheel 13. rlhe shaft 53 isprovided with a plurality of lifting arms 64, each of which is joined toan arm 65 of a beam 56 by means of a bolt 66.

A spring 67 is interposed between the arms 64 and 65 to permit theindividual seeding attachment to be raised independently of its 9adjacent units. y v

In order to enable the operator to stop the power feed, the sprocketwheel 61 is provided with a clutch jaw 68. The sprocket wheel 61 is freeto rotate on the sleeve 69 1 whose position is determined by the setscrew 70 which p-asses through the collar 71 and also the end of thesleeve 69. Meshing with the jaw 68 is a slidable jaw 72 having a squareopening to receive the shaft 52.

On the shaft 53 is mounted a cam arm 73, against whoseside bears thepin74 of the, clutch shifting.- 75 which is slidb'lyg mounted'inthebracket 76. Rotary motion is supplied to the shaft 53 through thehandlever 77, which can be held: position by the quadrant 78.

A tail skid 79, which adjustable, is provided to hold the beam 56, withits attached seeder parts, at the desired elevation. In this instancethe `planting siioefgsoradmits the Seedto.- the, ground. 81 in. thefurrow ispreviously made b. ,.the plow' 82,' ywliiclris also securedtothe 'earn ,but slightly in advance of the'shoe 80;`

In Fig. 5 is shown the manner in which a cultivator 89 can be attachedto the arm 65 for cultivating purposes, .which works out very well sinceall of the rows are planted in parallel relation to each other, it isjust as' easy to keep a number of cultivators between thejrows as it isone, since they are alli-securely? fastened togetlien and? tlierows areuniformly spaced.
